摘要:The present invention relates to a synthesis method of preventing the formation of impurities and byproducts in the synthesis of tenofovir disoproxil fumarate (Teno-DF) used as a medicine for hepatitis B and HIV treatment due to its function to promote bioactivities. In the synthesis method of the present invention, an ion-exchange resin (Dowex 50W hydrogen form, sulfonic acidic cation exchange resin) is used to enhance the yield and purity of the compound. The present invention also relates to a method of preparing an oral dissolving film dosage form in the manufacture of a medicine using the tenofovir compound with high purity obtained by the synthesis method of the present invention as an effective ingredient.
